what is TSS and why is it a concern?

Toxic Shock Syndrome (TSS) is a rare but serious bacterial infection most commonly linked to prolonged tampon use. It is caused by toxins produced by Staphylococcus aureus or Streptococcus pyogenes bacteria. Symptoms can develop quickly, so understanding how to use internal period products safely is important.

As more people explore reusable options like a menstrual disc, a common question is whether discs carry the same risks as tampons.

do menstrual discs increase the risk of TSS?

Current evidence suggests that menstrual discs have a lower risk profile compared to tampons. This is largely because a menstrual disc collects fluid rather than absorbing it. Tampons can create an environment where bacteria may grow more easily, particularly if left in for extended periods.

A reusable menstrual disc sits differently in the body and does not rely on absorbent fibres. While no internal product is completely risk-free, reported cases of TSS linked to menstrual discs are extremely rare. Following recommended hygiene and wear time guidelines helps reduce risk further.

what is a menstrual disc?

A menstrual disc is a flexible device worn internally at the base of the cervix. It collects menstrual fluid rather than absorbing it, which is one reason many people consider it a more comfortable option. Unlike a menstrual cup, a disc does not rely on suction and instead stays in place by sitting behind the pubic bone.

The my mimi reusable menstrual disc is made from medical-grade silicone and designed for flexible, everyday wear. It can be worn for up to 12 hours depending on your flow, making it suitable for workdays, sleep, and travel. Its design also includes a loop tab to support easier removal, particularly for those new to menstrual discs in Australia.

how to reduce the risk of TSS with a menstrual disc

Using a menstrual disc safely comes down to good hygiene and following product guidelines. Simple habits can help keep your experience comfortable and low risk:

• Clean your disc properly: Wash your reusable menstrual disc with warm water and a gentle, fragrance-free cleanser after use. Sterilise it between cycles according to instructions.
• Follow recommended wear times: Many menstrual discs can be worn for up to 12 hours, but it is still important to empty and rinse regularly based on your flow.
• Wash your hands: Always clean your hands before inserting or removing your disc to avoid introducing bacteria.

menstrual disc vs tampon: TSS risk comparison

Tampons have historically been associated with TSS due to their absorbent nature and prolonged contact with the vaginal walls. A reusable menstrual disc works differently by collecting fluid without creating the same environment for bacterial growth.

Because menstrual discs are smooth and flexible, they may also reduce friction against the vaginal walls compared to some absorbent products. For those researching the best menstrual disc option, this difference is often a key consideration.
